So I made Minecraft really impossible. You may know that a YT channel called "Fundy" made four difficulties. Three of them were a part of the Impossible mode he made. But this datapack makes Minecraft harder than his nightmare difficulty. The changes I made:
The zombie army (Zombie, husk, zombie villager, drowned and zombified piglin) will now always have full netherite armor with protection 4 and thorns 3 and op weapon.. A zombie will have a netherite sword with sharpness 5 and fire aspect 2 as the weapon and husk, zombie village, zombified piglin will have a netherite axe with sharpness 5 only as the weapon.. A drowned will have a trident with channeling as the weapon. Skeleton and stray will have power 5, punch 2 and flame in their bow but I didn't change their armor because of a reason. But they are still able to wear armor just like they do normally sometimes. I didn't make any changes to the creeper because I don't know how to make a creeper charged by commands. All the mobs now have regeneration 0 (Regeneration I) it means all the living mobs now will regenerate health! All the mobs also have fire resistance so if you get fire aspect or flame in your sword or bow, it's just useless. It will be always night so you will be able to sleep infinite times but it serves no purpose. And those op mobs will also always spawn. The difficulty will also be hard even if you start the world in peaceful it will become hard just after joining the world with this datapack. All the mobs that can have effects will now have speed V except golems. Your health will not regenerate automatically unless you use healing potions or golden apples. Even if you change the gamerule it will still remain the same. If you beat Minecraft with this datapack, you are more than a legend. Remember if you beat the game in creative or by using cheats you're not a legend.
